Abstract

A method for merging first and second digital video signals generated by first and second video controllers, respectively, for merged transmission to a digital video decoder. The first video controller transmits the first digital video signal to the decoder while monitoring the signal to detect a luminance component which designates the boundary between a first image constructable from the first video signal and a second image constructable from the second video signal. When the luminance component is detected, a colorkey signal is generated by the first video controller and transmitted to the second video controller to initiate transmission of the second digital video signal to the decoder in place of the first digital video signal. The first video controller continues to monitor the first video signal until the absence of the luminance component is detected. The first video controller then transmits a second colorkey signal to the second video controller to terminate the second digital video signal and transmission of the first digital video signal to the decoder recommences.
